Not just being polite here. I've engineered/produced several of these types of bands in the last 10 years.
First thing to note is that the kids' performances are fantastic! Drums, bass, guitars, keys, and even the vocals (especially on the latest track "Bang Your Head Wake The Dead") are all very tight! Lots of kid bands don't care this much about their music, don't practice enough, don't do 2nd, 3rd, 10th, etc. takes when they mess up a part in the studio. These kids obviously care a lot - it shows. Tell them to keep up the great work and they will only get better and better!
Second thing is the production is quite good. Nice job Mark. :)
Third thing is that the songs are also very good. This band is obviously talented and creative too. I hope they stay together for a long time.
